It’s unfortunate that Diaz, one of MMA’s most divisive (yet popular) and exciting fighters has decided to stay out of the sport while fighters like Matt Hamill have decided to grace us with their painfully mediocre presence once more.

(On the other hand, a noodling business venture with the Diaz brothers seems pretty tempting.)

Kron Gracie, son of family champ Rickson Gracie, won gold in the -77kg weight class of the 2013 ADCC tournament this past weekend. The ADCC is like the Olympics of submission grappling, with the world’s best meeting every two years to decide weight class champs as well as an open-weight champion.

Gracie won all four of his matches by submission, joining the elite ranks of former champions to have done the same like Marcelo Garcia and second cousin Roger Gracie. Kron beat UFC veteran Andy Wang in his first match, Gary Tonon in his second, J.T. Torres in his third and rival Otavio Souza in the finals.

Will Gracie decide to leverage his now champion status in the submission grappling world or walk away and make a name for himself in MMA? How much of a sense of urgency does he feel to focus all of his attention on developing a well-rounded MMA game?

Only time will tell but we’ll certainly bring you updates as they occur. For the time being, enjoy Kron’s 2013 ADCC matches against Tonon and Souza after the jump.

Earlier this week, Nick Diaz friend and teammate Gilbert Melendez (who fights Diego Sanchez this Saturday at UFC 166) offered his opinion that “I think with the right opportunity, for the right thing, [Diaz will] come out [of retirement].”

The first came after he lost a close decision to Carlos Condit and was then suspended for a failed drug test, and the second and current one came after he lost a tough decision to welterweight champ Georges St. Pierre last March. Diaz is only thirty years old but has been fighting professionally since he was a teenager and appears weary of taking part in anything short of mega-fights at this point in his career.

So, there’s really no new developments in this story yet until Nick himself comes out and…no, wait, Mike Bisping wants to tell us all something and he wants to do it while cooking steaks in his home.

In the above video, Fighters Only magazine visits with their countryman Bisping at home while the cocky Brit cooks dinner for his family. Bisping once more accepts the theoretical fight with Diaz and also talks about several other issues. Highlights after the jump.

Last spring former Nevada State Athletic Commission Executive Director and current UFC Vice President of Regulatory Affairs Marc Ratner publicly criticized the way that states like Nevada tested for Marijuana metabolites, and expressed hope that it would be changed.

Fighters competing while high should not be tolerated, the idea seemed to be, but punishing guys like Pat Healy for smoking weeks before fighting seemed harsh and silly. The World Anti-Doping Agency (WADA) recently upped the metabolite level that they tested for, and the tide appears to have fully turned now as the NSAC has “officially raised the testing threshold of marijuana metabolites from 50 ng/mL to 150 ng/mL,” according to a report on MiddleEasy.

We’re no marijuana experts but this change would seem to be a move by the world’s most influential athletic commission to stop penalizing recreational marijuana use by fighters, although testing for THC will continue because, while perhaps not performance enhancing, it is dangerous to fight high, drunk or in any other significantly altered state.

Now, Machida is saying that he has accepted a fight with Belfort and is using the “Phenom’s” own words to embarrass Vitor. “I’ve accepted the fight,” Machida recently told Globo.com, at least that’s what google translate tells us.

“And [I am] sure Vitor Belfort will accept, because, as he said, your son does not run from a fight.”

“I talked to Diaz today, and I made him an offer, so we’ll see what happens,” White said. “He had been talking about going to 185 pounds. [Lyoto] Machida has been talking about going to 185 pounds. So we wanted to see if he wanted to fight Machida at 185…They said they’d get back to me.”

Update:According to MMAFighting, Dana White is denying that he made any sort of bout offer “to Gracie or anyone else that reps Nick.” Huh. Maybe Cesar Gracie has fallen victim to the same mysterious troll that’s been offering Bellator contracts to people? Or maybe Dana just doesn’t like when managers tell tales out of school, so to speak.

The welterweight veteran sent a public message to Dana White a couple weeks ago and now, according to his manager, Diaz is considering an offer from the UFC. Cesar Gracie wouldn’t say who the offer is against during an interview with BJPenn.com, only that the proposed fight is ”kind of neat, I think. But no decisions have been made for sure.”

Whoa, long time since we had a “neat” fight in the UFC. Way to hype this possibility up, Cesar.

Last week, Nick Diaz posted a picture of himself with a woman he identified as his ex, and wrote “Never Post pictures of your girlfriend on Instagram Especially if you love her. #xgf #x #ftw #hatelife #might #have #to #slap #the #winner #tomorrow #need #a #fight #danawhite.”

As best as we could guess, Nick was saying that he wasn’t in a good emotional place right now, probably because of a recent break-up, and he wanted to fight the winner of UFC 162‘s main event between Anderson Silva and Chris Weidman. Now, Diaz calling out the winner of a middleweight title fight despite his two-fight losing streak at welterweight makes about as much sense as him saying not to post pictures of a girlfriend on an Instagram post where he posts a picture of a girlfriend, but dammit we were intrigued.

At the UFC 162 post event scrum, Dana White confirmed that Diaz had contacted him directly, asking to come out of his self-described retirement and fight again. “[Nick] texted me that he broke up with his girlfriend and he wants to fight,” White told reporters.

Following in the footsteps of his former promotion, Nick Diaz’s WAR MMA recently released a “Danavlog”-style video detailing the ins and outs of an upstart promotion in the days leading up to their first event, which went down last weekend to mixed results. Why anyone involved allowed MMAFighting’s E. Casey Leydon to do this, or release the specific footage that he did, defies the most basic entrepreneurial logic imaginable, but such is Nick Diaz.

The footage, which depicts Diaz’s crew of cohorts smoking weed (specifically resin, because what? You can’t smoke Cali Kush on a UFC salary), breaking into cars, and failing to even get their promoter to show up to the weigh-ins as promised (classicDiaz, amiright?), is damning evidence on almost every level. And yet, they allowed it to be released. Willingly. Like if the NSA had chosen to hand Edward Snowden the PRISM metadata, a Presidential Medal of Freedom and a first class ticket to Moscow on live television.

How an organization so haphazardly assembled even managed to pull off an event the size of WAR MMA without anyone dying is simply shocking when viewed through the hindsight goggles of this video, so join us after the jump as we marvel in the ridiculousness that is a Nick Diaz business venture.
